Benefits of technology
"The patent describes a system for performing minimally invasive surgical procedures using a cannula and a surgical instrument that can be positioned relative to the cannula using a position control mechanism. The system includes a position controller that can communicate with the position control mechanism through a communication path, such as a cable or wire. The position control mechanism can include a fixed element and an articulating element that can be moved relative to each other using a hinge or other mechanism. The system can also include additional tools for the procedure, such as introducer needles, guide wires, and hydraulic or pneumatic cylinders. The position control mechanism can be controlled remotely, allowing the surgeon to remain outside the radiation field. The system can also include a nozzle for delivering bone filling material to the target surgical location, with the nozzle being retracted or maintained in a specific position as the material is dispensed. The position control mechanism can be a fixed element and an articulating element, with the articulating element being moved relative to the fixed element using a hinge or other mechanism. The system can also include a valve at the distal tip of the nozzle to control the flow of material. Overall, the system allows for precise positioning of the surgical instrument relative to the cannula and minimizes the invasiveness of the surgical procedure."
Problems solved by technology
In contrast to an open procedure for the same purpose, a minimally invasive procedure will generally be less traumatic to the patient and result in a reduced recovery period.
For example, for many individuals in our aging world population, undiagnosed and / or untreatable bone strength losses have weakened these individuals' bones to a point that even normal daily activities pose a significant threat of fracture.
In one common scenario, when the bones of the spine are sufficiently weakened, the compressive forces in the spine can cause fracture and / or deformation of the vertebral bodies.
For sufficiently weakened bone, even normal daily activities like walking down steps or carrying groceries can cause a collapse of one or more spinal bones.
Fractures such as vertebral compression fractures often result in episodes of pain that are chronic and intense.
Aside from the pain caused by the fracture itself, the involvement of the spinal column can result in pinched and / or damaged nerves, causing paralysis, loss of function, and intense pain which radiates throughout the patient's body.
Even where nerves are not affected, however, the intense pain associated with all types of fractures is debilitating, resulting in a great deal of stress, impaired mobility and other long-term consequences.
For example, progressive spinal fractures can, over time, cause serious deformation of the spine (“kyphosis”), giving an individual a hunched-back appearance, and can also result in significantly reduced lung capacity and increased mortality.
Until recently, treatment options for vertebral compression fractures, as well as other serious fractures and / or losses in bone strength, were extremely limited—mainly pain management with strong oral or intravenous medications, reduced activity, bracing and / or radiation therapy, all with mediocre results.
Because patients with these problems are typically older, and often suffer from various other significant health complications, many of these individuals are unable to tolerate invasive surgery.
In addition, to curb further loss of bone strength, many patients are given hormones and / or vitamin / mineral supplements—again with mediocre results and often with significant side effects.
Unfortunately, due to the constrained access requirements of minimally invasive procedures, tools associated with such procedures have typically been designed to be manipulated in close proximity to the actual access location to the patient's body.

Embodiment Construction
[0027]By incorporating remotely activated position control capabilities, a minimally invasive surgical system can be used to effectively perform a minimally invasive surgical procedure while allowing the surgeon to remain outside the radiation field.
[0028]FIG. 1 shows a system 100 of functional instruments that can be used to perform a minimally invasive surgical procedure. In various embodiments, system 100 can comprise a kit providing a prepackaged set of instruments for performing the surgical procedure.
[0029]System 100 includes a cannula 110 and a surgical instrument 120 that is sized to perform a percutaneous procedure through a lumen 111 of cannula 110. System 100 further includes a positioning mechanism 150 that can be coupled to cannula 110 and surgical instrument 120, and a remote position controller 160 that directs positioning mechanism 150 to adjust the position of surgical instrument 120 relative to cannula 110. Note that according to various embodiments of the inventio...

A system for performing a minimally invasive surgical procedure includes a cannula, a surgical instrument for use through the cannula, and a remote positioning system to adjust the relative position between the surgical instrument and the cannula. By allowing a physician to perform the minimally invasive surgical procedure at a distance from the patient, the remote positioning system minimizes the radiation exposure of the physician while still providing accurate control over the procedure.
Description
FIELD OF THE INVENTION[0001]The invention relates to a system and method for performing a surgical procedure, and in particular, to a medical kit or system that includes a depth control mechanism that can be operated remotely.BACKGROUND OF THE INVENTION[0002]A minimally invasive procedure (sometimes referred to as a percutaneous procedure) is a medical procedure that is performed through the skin or an anatomical opening. In contrast to an open procedure for the same purpose, a minimally invasive procedure will generally be less traumatic to the patient and result in a reduced recovery period.[0003]For example, for many individuals in our aging world population, undiagnosed and / or untreatable bone strength losses have weakened these individuals' bones to a point that even normal daily activities pose a significant threat of fracture. In one common scenario, when the bones of the spine are sufficiently weakened, the compressive forces in the spine can cause fracture and / or deformatio...
